Solar inverter control switch principle
The inverter switch is the part that controls the on-off of inverter circuit. It controls the conversion frequency and direction of the transformer, so that the input direct current can be converted into the required AC power output to the load. The available inverter models are now very efficient (over 95% power conversion. . Whether the application is a solar calculator with a PV array of less than 1 W or a 100 MW grid-connected PV power generation plant, all that is required between the solar array and the load are electronic and electrical components. One of them is “Origin Wave Generator” for AC voltage, and the other is “AC generator” which produces a target AC voltage wave.
